Application October 7. 1936, Seriai No. raise:v '1 claims. (ci. rat-2st) My invention relates to brakes and more particularly to brakes for trucks, trailers, busses and the like where the conditions of brake operation are so severe as to cause rapid heating and destructive burning of the brake liners as well as the resultant distortion of the drum and other metal parts of the brake. v
, It is a purpose of my invention to provide in a brake, means by which the brake parts are subjected to the cooling action of water or other heat-dissipating fluid in a manner to maintain the brake parts at relatively low temperatures and thereby prevent overheating thereof even when the brake is continuously applied for protracted periods.
It is also'a purpose of my invention-to provide a wheel brake having chambers therein through which water is circulated by operation of a pump, and where automatic means is provided for rendering the pump active only when the temperature of water in the chambers rises. above a predetermined degree, and to maintain the pump in operation for such time after the water temperature is reduced to insure complete cooling of the brake.
I will describe only one form of brake, and two forms of pump operating and control means, each embodying ,my invention and will then point out the novel features thereof in claims.
In the accompanying drawings:
Fig. 1 is a view showing in sideelevation one form of brake embodying my invention with the bolts by which thabrake is secured to the axle, in
section.
Fig. 2 is a vertical sectional view taken on the line 2-2 of Fig. 1.
Figs. 3 and 4 are vertical sectional views taken on the lines 33 and 46, respectively of Fig. 2.
Fig. 5 is a horizontal sectional view taken on the line 5-5 of Fig. 1, with the drum omitted.
Fig. 6 is'a view showing in plan and somewhat in perspective four brakes constructed in accordance with my invention for the respective wheels of a truck, and one form of water circulating means applied to the brakes.
restrain rotation thereof in effecting braking of the wheel.
Thestator includes a brake pressure applying I member M which is of annular form and provided on its inner periphery with an annular flange i5 which is secured by bolts it to the flange i i of an axle A. This axle may constitute the axle housing for the rear axle of a truck, the front axle of a truck, or the dead axle of a trailer. The stator also includes an inner brake-pressure applying member M whichis likewise of annular form and supported concentrically on the outer member M to move axially toward and away from the latter but not to rotate relative thereto. To support the inner member in this manner three short lengths of pipe is are secured at their closed ends (Fig. 2) in bosses 2i. These pipes are loosely fitted in openings 22 in bosses 23 of the outer member M.
such that it is interposed between the members, M and M with the liners 32 adapted to have braking contact with the confrontingsides of the members.
For actuating the inner member M to cause such member to coact with the outer member.M
to have braking engagement with the element E,
the following mechanism may be provided: As
bestshown in Figs. 2, 3 and 5, a U-shapedyoke 34 is fulcrumed at its upper ends by pins 35 engaging within recesses 36 of the yoke and exends of a pair of rods 38. These rods 38 are loosely fitted in and extend through openings 3% in the outer member M, the outer ends of the rods carrying nuts 56 which limit movement oi the rods inwardly.
Just beneath the fulcrumed ends of thejyoke be rounded lugs M. engage shoulders 52 on the inner member M so that when the yoke is swung outwardly in a, counter-clockwise direction as when viewed in Fig. 2, the inner member will be moved toward the outer member to thereby cause the two members to have braking engagement with the element E. Such actuation of the yoke is effected through the medium of a rod 33 threaded in a clevis M pivotaliy connected to an ear # 35 on the yoke M by a pin # 35. The rod 33 carries a nut 33 for locking the rod in adjusted position in the clevis id. The outer end of the rod is provided with a clevis 36 in which is pivoted a lever ll by means of a pin iii.
As shown in Fig. 2, the elements just described,
with the exception of the lever M, are movable through suitable openings in themembers M and M, the lever being fulcrumed on a bracket 39 secured to the outer side of the outer member M. This lever is adapted to be connected to any suit-'- able mechanism (not shown) by which it may be pulled outwardly from the brake to effect actuatiorr of the yoke in the manner previously described. Such operation of the yoke is against 1 the tension of the several springs 2d, and thus threaded therein tubular cap screws 54 and 55 respectively, to which inlet and outlet pipes 3 and 55 are respectively connected by hubs 54 outlet ports 5'! (Fig. 3).
and 55' formed integral therewith. The member M is provided with one inlet port 56 and two In each instance the respective pipe i8 (Fig. 2) communicates with the respective port through a port 5% so that the chamber 5! is placed in communication. with the three pipesiB.
In the instance of the cap screw 27 for one pipe it, an inlet pipe 59 is screwed into the latter. In the instance of the cap screws for the other pipes, the opposite ends of a pipe 60' are screwed thereinto. The pipe 63 is of Y-form to provide a common outlet pipe 6!. The purpose in providing two outlets for the chamber 5! is to effect a more free circulation of water through the chamber in order to dissipate that excess heat to which the inner member M. is subjected by reason of it being substantially housed within the drum 29.
For the purpose of circulating water through the four brakes of a motor truck or bus where each brake is constructed in accordance with my invention, I provide, as illustrated in Fig. 6, a rotary-pump 52 connected at its outlet side to a header G3, and at its inlet side to a radiator 66. Through tubes 65 and branch tubes 66 the header 63 is connected to the inlet pipes 55% and 59 to place the chambers 58 and 511 of each brake in communication with the header, the radiator active.
amass? tending through clevises 3? fixed on the inner being provided for the purpose of distributing water evenly to all brakes. Return pipes 611 and branch pipes 675 connect the outlet pipes 5!.5
and hi to the radiator 66, and thus through the tubesfie and 61 and their branch tubes is provided a line by which the pump is placed in cirguitk communication with the chambers of all four ra es.
The pump M has a shaft M which, by meansof gears 6%, is operatively connected to a countershaft: 18. Through a conventional clutch the shaft it is adapted to be connected to a driving shaft ii which may be driven from the transsure with temperature, and which pressure is conveyed to the diaphragm to actuate the latter when reaching a predetermined degree.
In operation, when the water in the brake to which the diaphragm casing is connected, is below a temperature to which the brake is not excessively heated, the clutch is in the disengaged position shown in Fig. 6 to render the pump in- However, when the brake temperature rises to a detrimental point, the fluid pressure imposed on the diaphragm rises. accordingly to actuate the diaphragm and thus move the clutch to engaged position in which the pump is set into operation to circulate water through all brake chambers and to thereby efiect cooling of the brakes. As this cooling is effected, the .water is likewise cooled by the radiator. As the fluid is slow in returning to its normal pressure, the diaphragm is likewise slow in returning the clutch to disengaged position. Hence, the pump remains in operation for a limited time after the. water is cooled to insure thorough cooling of the brakes before water circulation ceases.
Referring now to Fig. 7, I have here shown my brake applied to one wheel of a two wheeled trailer, and another form of pumpoperating Y means. In this embodiment of my invention a pump 80 and a radiator 8! are suitably mounted upon the axle A. The discharge side of the pump is connected by a pipe 82 and branch pipes 83, 83'
to the inlet pipes 55 and 59. The intake side of the pump 80 isconnected to the top of the radiator 8| by a pipe 84, while extending from the bottom of the radiator is apipe connected to the outlet pipes of the brake through branch pipes 86, 86. Thus, the chambers for one brake are placed in circuit communication with the pump and radiator. The chambers of the other brake (not shown) for the other trailer wheel (not shown) may be placed in circuit communication with the pump and radiator by pipes 81 and 88, as will be understood.
The pump 8!] is operated by a wheel 89 fixed to the shaft 68 and having frictional contact with the outer periphery of the drum 29. Thus, rotation of the drum actuates the pump to circulate water through both chambers of both brakes to efiect cooling of the latter, the water, in turn, being cooled by the radiator as it is circulated therethrough.
